MBDB is a synthetic phenethylamine similar in structure and action to MDMA (Ecstasy). It is an entactogen, with the ability to facilitate a state of introspection, interpersonal communication and a pronounced sense of empathy and compassion.

MBDB has a slower and more gentle onset of action than MDMA, produces less euphoria, less psychedelic effects, and has less stimulant properties. Many people find MBDB less fun than MDMA because of its more subtle nature and lack of strong rush. MBDB is extremely uncommon, but has occasionally been found in "ecstasy" tablets in Europe.

Do not take MBDB if you are currently taking an MAOI. MAOIs are most commonly found in the prescription anti-depressants Nardil (phenelzine), Parnate (tranylcypromine), Marplan (isocarboxazid), Eldepryl (l-deprenyl), and Aurorex or Manerix (moclobemide). Ayahuasca also contains MAOIs (harmine and harmaline). MBDB and MAOIs are a potentially dangerous combination. Check with your doctor if you are not sure whether your prescription medication is an MAOI.
